Description

A constructor for SMAPHMM-class objects.

Usage

2
3
SMAPHMM(noStates, Phi, A=NULL,
        Pi=rep(1/noStates,noStates),
        initTrans=0.2/(noStates - 1))

Arguments

noStates

The number of hidden states in the HMM (numeric).

Phi

A Gaussian distribution parameter matrix (numeric).

A

A noStates * noStates matrix of transition probabilities betweeen the hidden states (numeric).

Pi

A vector of initial probabilities of starting in a certain state (numeric).

initTrans

Specifies the transition probability between non-equal states (numeric).

Details

Phi is a noStates * 2 matrix that specifies the paramaters of Gaussian distributions associated with each hidden state. The first column specifies standard deviations, the second specifies means.

If A == NULL, initTrans specifies the transition probability between states i and j in 1:noStates, such that i != j. Only used if A == NULL. initTrans * noStates must be smaller than (or equal to) 1.

Value

An object of class SMAPHMM-class.
